knockout.js - Bind a <select> to an array in knockoutjs? -

-
i have checkbox list on page bound knockout observablearray. when checkboxes selected knockout updates observablearray expected [123, 345, 456] (if 3 options in checkbox list selected) it fires off few functions goes through array , bunch of things. my trouble want able switch between using checkbox list , <select> . single select vs multiselect, using same ko.observable... these functions don't work when it's flat string , not array. when using <select> , there way can observable function single value array? e.g using select... <select data-bind="value: myobservable"> i want make selected value in myobservable be: ["123"] (or [123]) instead of plain string "123" you can use selectedoptions binding instead of value . <select data-bind="selectedoptions: myobservable"> if need multiple selection can use multiple="true" : jsfiddle

i need phone numbers textarea users collection.how can do? smsnumaralar=textarea template.uyeleresmsgonder.events({ 'click #numaralarikopyala': function (e, template) { var getdata=meteor.users.find({}); template.$('#smsnumaralar').val(getdata.profile.phone); } }); you can extract array of phone numbers using map , join given separating character (a newline in example), , put newly created string of phone numbers in textarea: template.uyeleresmsgonder.events({ 'click #numaralarikopyala': function (e, template) { var phonenumbers=meteor.users.find({}).map(function (user) { return user.profile.phone; }).join('\n'); template.$('#smsnumaralar').val(phonenumbers); } });

How is the data used for speech recognition collected and prepared? -

-
as far can tell, speech recognition implementations rely on binary files contain acoustic models of language trying 'recognize'. so how people compile these models? one transcribe lots of speeches manually, takes lot of time. even then , when given audio file containing speech , full transcription of in text file, individual word pronunciations still need somehow separated. match parts of audio correspond text 1 still needs speech recognition. how gathered? if 1 handed on thousands of hours' worth of audio files , full transcriptions (disregarding problem of having transcribe manually), how can audio split @ right intervals 1 word ends , begins? wouldn't software producing these acoustic models already have capable of speech recognition? so how people compile these models? you can learn process going through c musphinx acoustic model training tutorial one transcribe lots of speeches manually, takes lot of time. this correct, model prepa...

c - Floating point conversion - Binary -> decimal -

-
here's number i'm working on 1 01110 001 = ____ 1 sign bit, 5 exp bits, 3 fraction bits bias = 15 here's current process, can tell me i'm missing something convert binary exponent decimal 01110 = 14 subtract bias 14 - 15 = -1 multiply fraction bits result 0.001 * 2^-1 = 0.0001 convert decimal .0001 = 1/16 the sign bit 1 result -1/16, given answer -9/16. mind explaining 8 in fraction coming from? you seem have correct concept, including understanding of excess-n representation, you're missing crucial point. the 3 bits used encode fractional part of magnitude 001 , there implicit 1. preceding fraction bits, full magnitude 1.001 , can represented improper fraction 1+1/8 => 9/8 . 2^(-1) same 1/(2^1) , or 1/2 . 9/8 * 1/2 = 9/16 . take sign bit account, , arrive @ answer -9/16 .
